Want this question answered?
some chemical changes can be reversed but they are hard to reverse usually
Not necessarily. In some chemical changes a compound is broken down into its elements.
Some chemical changes when you are cooking are:burning the foodOVERcooking itUNDERcooking itsorry for only three examples. those are the ones that i can only think of so far.
non example of chemical change: one non example is ice. ice is NOT an example of chemical change.
Being ductile, malleable, freezing, melting are some examples of physical changes of a substance. Physical changes do not form a new substance while chemical changes do. Examples of chemical changes are a rusting nail and combustion.

Some chemical changes are reversible, others are not.
Freezing a popsicle
the wind has been changing and they have found gas in the desert but it is almost gone.
Not necessarily. In some chemical changes a compound is broken down into its elements.
because it mixes substances that makes a chemical change
The result of the rust colored tint of desert landscapes are to show chemical weathering. This is shown on a map.

I would argue that in theory all chemical changes are reversible. However it is certainly true that considerations of enthalpy and entropy mean that some are totally impractical to reverse.
There are no physical changes. there are only chemical changes.
Chemical changes that release energy are called Exergonic in biology, and Exothermic in chemistry. An example of these is respiration and fermentation.
